Agriemach, for what it's worth, said that the paint was pretty much an aesthetic thing as much as anything, as on a Scoob, there isn't a great deal of additional protection required.

As metal is non absorbent, paint would adhere to surface imperfections. Exhaust wrap being a woven material (just like my tee shirt
), doesnt have pores it does however does absorb paint. Try looking at some which has been removed.
If you apply enough to prevent ingress of water or oil it will have penetrated right through to the pipework.

. It doesn't need to soak in to adhere. Exhaust wrap just isn't just a nice material like your t-shirt. its heavily impregnated to cope with the high temps. The paint will help seal some of the pores but will not just 'soak in'.

Or maybe i should ask if you think fibreglass, silica or cermaic products are absorbant. Plus most have a proprietary top coat applied too.
Oh... and why do some quote:
"Often used in marine applications as it does not absorb moisture".
It is nothing like a bloody t-shirt![Roll Eyes (Sarcastic)](images/smilies/rolleyes.gif)

hi guys
i have no interest in exhuast wrap myself but i had come across something similar which the classic car guys are using with great results they tell me, on thier healeys and mgb's etc and you can get it from rallyused parts .co.uk.I hope it helps.
desciption "Twin layered aluminium heat shield. You can see this high performance material in some recent production cars. It is a highly efficient thermal barrier and also has effective acoustic damping characteristics.
Example of heat reduction:
Exhaust temperature of 500C, metal panel 25mm away. Without a heat shield, metal panel reaches 274C. With Nimbus inbetween, metal panel reaches only 85C !!
For more technical information email rallyused parts
Available in 500 x 200mm sheets in a pack of 5.
Nimbus GII can be bent very easily into all sorts of shapes and can also be cut with scissors."

So when you spray your wrap with water, the water isnt absorbed by the wrap then? Of course not thats why the wrap doesnt become more flexible, and of course if you do not paint the wrap, then it obviously remains impermeable to moisture (the original reason for painting wrap is to protect it from oil and water)
Just because the fibres the wrap is woven from do not individually absorb moisture doesnt mean that the woven wrap will not absorb moisture.
Exactly like any "bloody" tee shirt or sponge, manufactured from man made fibres. Ever heard of capillary action?

Hi All
I bought a brand new set of header's and wrapped them individually( I.E every pipe seperate) and i used 2 roll's of 1"*50' for this job, this also aloowed me to wrap the uppipe as well.
I also bought 1 can of black paint, sprayed the lot twice and still had some left over.
Just a guide to what i used that's all.
Cheers Dougie

Yes i know what capillary action is and yes the wrap is used in marine applications and is quoted as NOT absorbing moisture. Do you want to take the manufacture to court for false claims???? So what is your point? You initially said that the paint reduces the insulation properties of the wrap because it has lower thermal properties than the wrap. Yes it does have lower thermal properties but it does not replace any of the wrap, it adds to the thermal mass. You then said the wrap absorbs the paint.... i'd say it sticks to the imperfections on the fibre/silica and the top coat and seals the pores, thus protecting it from the ingress of moisture through the pores. I still don't get your point. Do you want to explain properly to everybody why you think the paint reduces the thermal properties of the wrap.
Tony.

Hmmm might well be in the market for sum adhesive reflect a cool stuff. Forgive me if it's already been asked but are we looking at a time frame when this will no longer be available at discounted rates?

Received the goods that i ordered at end of last week, today, which is spot on and can recommend them if my experience with them is anything to go by.
I bought more than i needed but as i said in an earlier post, it won't go to waste.
Just thought i'd let you know how i got on with the company and no problems in dealing with them at all. Nice.![Smile](images/smilies/smile.gif)
As for how much is needed... Dyney posted this on the first page
so this should give you an idea.
